Don't forget too that if you're talking about 'new' videos, your views will be calculated before the estimated revenue, the revenue usually lags 2-3 days behind view counts. So if you're looking at total current views and total $$ earned, there's most likely a couple days of earnings not counted yet.
I also think you're getting CPM mixed up with RPM? If you get $3.00 for 1,000 views, that's your RPM, your rate per thousand views. CPM is a gross number that advertisers are paying per thousand views and is before any cuts are taken (if I understand all this correctly).
I would 'guess' that the majority of channels getting substantial views (big enough views so the law of large numbers can play out) the RPM probably ranges from $1 - $3. The RPM could vary even more depending on your niche (some niches, like expensive high-tech stuff, can pay a lot more for someone to watch ad add because it's more valuable, but might get less clicks because of it). The number of views YouTube calculates as views will usually be quite a bit higher than what Adsense calculates as views because Adsense is based off monetized views and as it was stated, even if your videos are all monetized, that doesn't mean an ad is always run on it.[DOUBLEPOST=1427743003,1427742588][/DOUBLEPOST]Personally I'd like to see a minimum threshold of subs and views before someone can monetized their channel, the ad rates are so low now because there's a katrillion videos for supply, even if a channel has one or two videos with hardly any views or subs, and there are tens/hundreds of thousands of those, they're still sucking up ad revenue, pennies for them but with so many, it's big $$ overall. YouTube doesn't care as much because they're getting the $$ just the same no matter what generates it, but it's taking the floor out from the serious YouTubers trying to produce high quality content for a living. We're personally still doing very well because our views are very strong but the RPMs seem to be lower compared to each prior year for the same period. It takes huge views now to make 'real' $$. But that's not a complaint, just a suggestion. YouTube put minimum sub thresholds to create your own custom URL, I think the same should apply for monetization. You're not really making hardly anything with such small views anyway, might as well make a minimum threshold to help ad inventory.
